Topic: Choose one game to last you for eternity

Everybody posting here is not playing monster hunter.

Can't speak for everyone, but you're right that I don't play it. Is the single-player experience still that good then?

Come on, I'm just about to go to bed. I can't play it all day

Monster Hunter or Animal Crossing. It's a tough choice, but I'd have to say MH wins here.

3 choices for me: Kid Icarus Uprising, Majora's Mask 3D, or Pokemon X/Y. Probably X/Y.

Super Smash Bros Wii U.

Because eventually you become the Monster Hunter God, charging your GS in some seemingly random direction. Then the Kirin walks into it just as the third flash appears.
QUEST COMPLETE!

With that every hunt, it's just not the same.

Dwarf Fortress, on the other hand, is the Grandpappy of Minecraft and the hell-spawn of Nethack. The game random-generates an entire world's several-hundred-year history, complete with mythical beasts with seven arms, five legs, and thirty-two eyes, ordinary people that kill said beasts then become heroes, kings that lead regimes then go insane, elf-hating elf-kings of dwarves, and lots and lots of zombie sponges. And each one of these has a fully functional nervous system (except the sponges).
In other words, on my choice of game, it was inevitable.

I'd take Tetris: The Grand Master 3 to keep it challenging.
